## What is Duo Reversi?

Duo Reversi is reversi played with two-cell pieces.

Every piece covers two cells side by side. Place a piece so that it sandwiches your opponent in a straight line — across, up and down, or diagonally — and their pieces flip to your color.

The twist: if only ONE half of a piece is sandwiched, the WHOLE piece flips. One move can swing the board, and a lone empty cell surrounded on all sides can never be filled. Plan ahead, read your opponent, and finish with more cells than they have.

FEATURES
